Comparisons were made in the C 1 generation between the untreated controls (2x) and colchicine‐treated diploids (C2x) for variation of leaf mesophyll cell size and chloroplast number. Differences were found in that the cell section area and the number of chloroplasts per cell in all the seven lines investigated were significantly greater in the C2x selections compared with the 2x controls using coded determination. In each case, there was an enhancement of chloroplast number independent of the variation in cell size.
